GASOLINE PUMP AND A VALVE THEREFOR Filed Dec. 1929 2 Sheets-Sheet 2 FREDERICK F. RIKE,

Patented July 18, 1933 v UNITED OSTATEVS PATENT FREDERICK F. BIKE, OF DAYTON, OHIO, ASSIGNOR TO BUOKEYE IBON AND BRASS WORKS, OF DAYTON, OHIO, A CORPORATION OF OHIO GASOLINE PUMP AND .41 VALVE THEREFOR Application filed December The object of this invention is to provide in connection with gasoline pumps an improved valve to prevent the back-flow of gasoline into the storage tank.

It is particularly the object of this invention to provide a valve of this kind, located between the supply tank and expansion chamber on-one hand, and the meter and the dis charge hose on the other hand, so that the me- 1 ter and the discharge hose may be removed without the escape of gasoline from the expansion chamber.

It is also an object of this invention to provide a valve for the purposes here described, in which the flow of the liquid through the valve chamber will not tend to cause the valve to seat and prevent the flow of the liquid. For this purpose there is provided a baifie plate slightly larger than the valve upon which the valve rests during the flow of the liquid through the delivery pipe so that the gasoline is diverted around the valve and does not tend to seat the valve during the process of the delivery of gasoline through the supply pipe and the discharge hose.

It is also an object of this invention to provide in connection with a valve of this kind means whereby the valve may be operated by the hose nozzle hook. 1 Not only may the valve be operated by the hose nozzle hook but at the same time the connection between the source of power to the motor is either closed or open. For instance, when the hose nozzle is applied to the hook the valve is closed 5 and the current is cut off, whereas when the hose' 'nozzle is removed from the hook the valve is opened and the current is connected so that the motor operates to actuate the pump to force the liquid through the supply pipe and the delivery hose to the customer.

These and other advantages will appear from the description taken in connection with the drawings.

Referring to the drawings:

valve upon the removal ofthe hose, or the location thereof upon the hook.

Figure 5- is a section onthe line 55 0 Figure 3.

Figure 6 is a section similar to Figure 3 but showing the valve openand resting upon the baflie plate.

The particularform of gasoline pump and easing therefor is no part of this invention. The invention lies in providing, in connection with the pump mechanism as generally shown in Figure 1, a valve to prevent the back-flow of gasoline after the delivery hose has been hung upon the hook so that the meter and the upper part of the delivery pipe orsupply pipe may be removed without the gasoline escaping from the expansion chamber back into the reservoir, from which the gasoline was originally pumped. u The casing of the pump is indicated by the numeral 1, below which there is the usual supply tank, not shown, from which there extends theusual pipe 2 leading to a strainer 3. Forming a continuation of the pipe2 is a supply pipe 4. The numeral 4 is applied to all sections of the pipe extending from the strainer to the delivery hose and includes whatever might constitute an integral part of this conduit when speaking of the supply pipe as a whole.

For the purpose of forcing the gasoline from the reservoir up through the supply pipe there is provided a pump which has a shaft 5. The particular form of pump forms no part. of this invention. On this shaft 5 is a sprocket wheel 6 for the purpose of operating the pump. The numeral 7 indicates a motor havingfa motor shaft8 with a sprocket wheel8 on the end thereof. Connecting the sprocket wheels 8 and 6 is a sprocket chain 9. Extending from the supply pipe 4 beyond the pump is a bypass pipe 10 which extends through a by-pass valve 11.. The purpose of this valve is to permit the return of the gasoline to the reservoir whenever a predetermined amountof pressure has been created in the expansion chamber and in the delivery hose.

The expansion chamber is indicated by the numeral 12 and has connection both with the pipe 10 and the supply pipe l so that whenever the gasoline is being. pumpeda certain amount that enters into this chamber creates an air pressure which tends to maintain a certain amount of pressure regardless of whether the pump is running or not. When this certain amount of pressure is exceeded the bypass valve opens, whereby the pressure is relieved.

Just above the pump and adjacent the e);- pansion chamber is located a valve casing 13 forming a part of the supply pipe. The nature and structure of this valve will be described later. Located in connection with the supply pipe is a meter 14; for the purpose of determining the quantity of gasoline flowing through the supply pipe and the delivery nose to the customer. The hose is indlcated by the numeral 15 while its nozzle is ind'catedby the numeral 16. I

For the purpose of supplying current to the motor and also to any lights that may be located on the pump there is aconduit 17 which provides housing for conductors 18. It will be observed that the conduit 17 branches oif to the motor at one place, and at another place it branches oif and has connection with the valve'13 of the valve casing. The purpose of this is that in the operation of the valve connection is made whereby the current may pass through the motor to operate the pump at the same time the valve is open, but when the valve is closed the current is cut off, the motor is stopped and no pressure is upon the gasoline to force it through the pipe except that which is within the expansion chamber, and when this pressure increases beyond a predetermined extent it is relieved by means of the bypass valve 11. j

The valve casing is shown in section in Figures 3 and 6, and as shown there consists of two sections, a lower section 19 and an upper-section 20. The parts of these sections where they unite are enlarged to form a chamber therein, and are united to each other at this point by means of threads 21. The lower chamber adjacent the threaded part thereof for receiving oneend of the section 20 has a baiiie plate 22 suitably supported therein so that there is provided a passageway for the gasoline around the ba -e, plate and between the sides of the casing. This baffle plate is circularv in shape and has eX- tending through the center thereof a hole 23 I which receives a valve'stem and guides the valve in its movement longitudinally of the .casing. The valve is indicated by the nn- 1neral 2 l and has extending therefrom a pluralit-y of guides 25 which engage the sides of the passageway 26 adjacent the valve seat.

The valve has a lower stem 27 which slidably ts within the hole 23 in the baiile plate. It also has an upper stem 28 provided with a slot 29in which an arm of a shaft 30 fits and operates. The shaft 30 is located in one side of the casing and has extending therefrom an arm 31 which projects into the slot 29 for the purpose of operating the valve. On the outside of the casing and extending from the shaft 30 is second arm 31, to the end of which there is attached one end of a link 32. This link 32 is attached at its other or upper end to a hose hook lever 33 pivoted at a suitable point 34 to the tank casing. The outer end of the lever 33 is formed into a hook 35 to support the nozzle of the hose. The hose is indicated by the numeral 15 while the nozis indicated by the numeral 16;

in the nozzle there is provided anozzle valve lever 36 for operating a nozzle valve, not shown. From an examination of Figures 3 and 6 it is obvious that when the valve is in the position shown in Figure 6 the gasoline passing through the pipe will be diverted to one side of the valve and will have no tendenvy toclose the valve. At the same time when the valve is in the position shown in Figure 3 the pressure produced by the gasoline would tend to close the valve and to prevent any unwanted flow of liquid through the valve casing. The pressure, however, tending to close the valve is not such as would interfere with its operation by means of the hose hook lever by placing thereon and removing therefrom the hose nozzle.

I desire to comprehend within my invention such modifications as maybe clearly embraced within my claims and the'scope of my invention.

Having thus fully described my invention, what I claim is new and desire to secure by Letters'Patent, is:

1. In a gasoline dispensing apparatus, a casing, said casing having a valve'seat therein, a valve in said casing having guide fins engaging the casing around the seat, said valve being adapted tooccupy said seat and operable against the stream of gasoline through the casing to open a passageway for the gasoline, and means in sa1d cas ng to" guide and prevent said stream oflgasoline closing said valve when it is open. v V

2. In a gasoline dispensingappara-tus, a valve casing, said casing having. an inlet and anoutlet, a valve seat in said casing between theinlet and the outlet, a baiile plate in said casing between the inlet and the valve seat, a valve partly guided by the plate between the baiile plate and the valve seat adapted to close said passageway when seated and to rest on said baiile plate when open in such manner that the baflie plate will divert the gasoline around the valve and prevent its beingclosed by the flow of gasoline, and fins on the valve engaging the casing to guide the valve and adapted to give direction to the fluid after passing the baifleplate.

3. In a valve mechanism, a casing, a valve having thereon guide rim engaging the casing in said casing, means to open'and close said valve, and a baffle plate to support said valve when open, said bafiie plate being somewhat larger than said valveso that liquid flowing around the valve through the casing will not close the valve.

4. In a valve mechanism, a casing having an inlet and an outlet, a valve in said casing, a stem on said valve extending toward the inlet, guide fins on the stem engaging the casing, and a bafifle plate between said valve and the inlet, said baflle plate being somewhat larger than the valve and having a hole therein for said stem, whereby the fluid passing through the casing is diverted around the valve without tending to close it and whereby the valve is guided while being opened and closed.

5. In a valve mechanism, a casing having a passageway theret-hrough, a valve having a slotted stem in said passageway, means to guide said valve and to support it and divert a fluid passing through said passageway 7 around it when open, and a shaft having an arm extending mto said stem to open and close said valve.

6. In a valve mechanism, a-casing having a passageway therethrough, a valve having a slotted stem in said passageway, disc means in said passageway to guide said valve and to support it and divert a fluid passing through said'passageway around it when open, and a shaft rotatably mounted in said casing and having an arm extending into said stem, whereby thevalve may be opened and closed. 7 In a valve mechanism, a casing having an inlet section and an outlet section, one end of each section being threaded to receive a pipe, the other end of each section being enlarged and threaded one into the other, a round baffle plate formed in the enlarged end of the inlet section, a valve member in the out-let section, saidvalve member having a stem on one side guided by said baflie plate and a slotted stem on the other side extending toward an outlet, and a shaft rotatably mounted insaid outlet section having an arm extending into the slotted stem, said, bafile plate being somewhat larger than the valve member in open position and deflects a fluid flowing through the casing around the valve and thereby prevents seating of the'valve.
